Reflection type electronic energy saving lamp
Technical field
The present invention relates to energy-saving lamp, particularly a kind of reflection type electronic energy saving lamp.
Background technology
Reflecting lamp is widely used in the directional lighting in places such as market, show window, exhibition, and used bulb is the structure of incandescent lamp formula mostly, as R type series or BR type series; Used bulb also has the structure of Halogen lamp LED formula, as PAR type series.Because the reflecting lamp energy consumption of incandescent lamp formula or Halogen lamp LED formula structure is big, light efficiency is low, heat is high, the life-span is short, now replaced by energy-saving lamp.
Uses at present with power saving fluorescent lamps as shown in Figure 1 as the reflection type electronic energy saving lamp of light source, reflect cell-shell 1 inwall skirt body region at electricity-saving lamp and scribble reflecting medium, the upper end printing opacity of cell-shell 1.In cell-shell 1 inside power saving fluorescent lamps installing rack 2 and power saving fluorescent lamps 3 are housed.Electronic ballast component 4 is for power saving fluorescent lamps 3 work.When assembling electricity-saving lamp product, the bore end D2 of reflection cell-shell 1 bottom is inserted in the outside of power saving fluorescent lamps 3 total outer diameter D 1, be connected with lamp body shell 5, the bottom of lamp body shell 5 is connected with lamp holder 6.
Total outside dimension D1 of the power saving fluorescent lamps of this electricity-saving lamp product must when the overall dimension of lamp body shell is restricted, also limit total external diameter of fluorescent tube less than the caliber size D2 of reflection cell-shell.As reflector lamp, its reflectivity curve has requirement, and when the bore D2 of reflection cell-shell strengthened, the reflection cell-shell will become straight-tube shape, will not have reflecting effect thus.Therefore, the bore end dimension D 2 of reflection cell-shell need be made the smaller the betterly, and this just makes that total outside dimension of fluorescent tube can not be too big, and just the power of fluorescent tube can not be done greatly, it is also little that power is done little certain brightness, the weak point of the maximum of prior art that Here it is.
Summary of the invention
Task of the present invention provides a kind of improved reflection type electronic energy saving lamp, and it has solved the total outside dimension of above-mentioned existing in prior technology power saving fluorescent lamps can not be too big, and power of lamp tube is done the also little problem of little brightness thus.
Technical scheme of the present invention is as follows:
A kind of reflection type electronic energy saving lamp, it comprises housing, the power saving fluorescent lamps installing rack of in housing, settling, be installed in the power saving fluorescent lamps on the installing rack, and electronic ballast component and lamp holder, the rightabout larger diameter end that becomes with lamp holder of described housing is designed to the opening shape, at open end the printing opacity light cover is housed, the internal diameter size of this open end is greater than the outside dimension of power saving fluorescent lamps, and the outside dimension of this power saving fluorescent lamps is greater than the size of the bore end of this lower housing portion.
Electricity-saving lamp of the present invention makes total outside dimension D1 of power saving fluorescent lamps to do maximumly in the volume scope of reflection housing owing to installed the printing opacity light cover, and the surface area of power saving fluorescent lamps is big more, and power is also just big more, and output brightness is also just high more.Electricity-saving lamp of the present invention owing to be not subjected to the restriction of the total outside dimension D1 of fluorescent tube, can make the installation bore end D2 of housing be designed to minimum dimension again, has increased the reflectance coating area of reflection housing simultaneously, and the corresponding light reflection efficiency that increased.
In addition, because installing bore end D2, housing of the present invention can be designed to minimum, make lower housing portion also can be designed to minimum, thus the akin overall dimension of reflector lamp of acquisition and incandescent lamp or Halogen lamp LED structure, for providing convenience with the fit applications of original light fixture.Housing of the present invention also can be made into integral housing, directly is connected with lamp holder.

Embodiment
Referring to Fig. 2 and Fig. 3, reflection type electronic energy saving lamp of the present invention is equipped with housing 11, settles power saving fluorescent lamps installing rack 12 in housing 11, installing power saving fluorescent lamps 13 on installing rack 12.Electronic ballast component 14 also is installed in housing 11.Lamp holder 15 is connected with an end of housing 11.
15 one-tenth rightabout larger diameter end of the other end of housing 11 and lamp holder are designed to the opening shape, at open end printing opacity light cover 16 are housed.As shown in FIG., the internal diameter size D3 of housing 11 open ends is greater than the outside dimension D1 of power saving fluorescent lamps 13, and the outside dimension D1 of power saving fluorescent lamps 13 can make power saving fluorescent lamps 13 inwardly install from housing 11 openends greater than the dimension D 2 of the bore end of housing 11 bottoms like this.
Printing opacity light cover 16 is chimeric connection or bonding connection with being connected of housing 11 open ends.Printing opacity light cover 16 is made by transparent glass or light-passing plastic.
As shown in Figure 2, housing 11 comprises the reflection housing 111 that is installed in power saving fluorescent lamps 13 peripheries and is installed in the coupling housing 112 that reflects between housing 111 and the lamp holder 15 that housing 11 is made up of reflection housing 111 and coupling housing 112.
As shown in Figure 3, housing 11 is an integral housing, directly is connected with lamp holder 15, makes moulded more perfectly, and has water resistance.Connecting conducting wire in the housing 11 between electronic ballast component 14 and the lamp holder 15 passes through position 18 at housing 11 and is also sealed by the gummed connection, to obtain better water resistance.
The inner reflective wall of housing 11 is coated with reflecting medium layer.Reflective film or reflection sheet can be pasted or be equipped with to the inner reflective wall of housing 11 also, can obtain reflecting effect equally, but simplify production technology, saves this step of coating process.
Power saving fluorescent lamps 13 shown in the figure is shape in the shape of a spiral, also can be bend pipe shape or straight tube shape, perhaps is other shape.The shape of housing 11 and euphotic cover 16 can be an Any shape.
